I have read some posts on StackOverflow. seems there might be possible for us to use offline map.

all we need to do seems to :

1. get some map files from google map, there are tools
2. convert it into formats that iOS can recognize.
3. put it into Maps.app cache file.

have no idea whether this need a jailbreak or not.
